Development of an IoT-Based Smart Nurse Call Using ESP32 and MQTT to Support Smart Healthcare at Bina Sehat Hospital Jember
The rapid advancement of Internet of Things (IoT) technology has accelerated digital transformation in healthcare services, particularly in communication systems between patients and healthcare personnel. Conventional nurse call systems generally rely on wired communication and local alarm indicators, limiting flexibility and centralized monitoring capabilities. This study aims to develop an IoT-based Smart Nurse Call system using ESP32 microcontrollers and the Message Queuing Telemetry Transport (MQTT) protocol to support smart healthcare implementation at Bina Sehat Hospital Jember. The proposed system consists of patient nodes, wireless communication networks, MQTT brokers, and a web-based monitoring dashboard. ESP32 modules are utilized to transmit patient requests through Wi-Fi networks, while the dashboard displays room identification, call status, and service history in real time. System performance evaluation demonstrated an average end-to-end communication latency of 72.4 ms with 100% message delivery rate under QoS Level 1 configuration, supporting up to 8 simultaneous patient nodes with latency below 100 ms. The integration of ESP32 and MQTT provides a flexible, scalable, and cost-effective communication platform suitable for healthcare environments. The developed system demonstrates the potential application of IoT technology in supporting healthcare digitalization and smart hospital initiatives.
